- .INl/ENTOR E/T H139 "77S ,By /d will be moved towards or from the beam'2 and as the bifurcated ends of lthe lever 23 v adjacent the rearlevers may be readily engagement when the have wheels 28 rotatablymounted between their extreme lower ends, the beam 2 will be raised whenthe lever is movedy rearwardly and correspondingly lowered when thelever is moved forwardly and: by providingy the rack bar 21 andcooperating latch-22, it will be seen that Vsaid beam maybe readily heldin its adjusted position. v I

Y In Iorder to place the levers 23 readily accessible to the operator, aseat 29 is secured end of the frame 1, which is midwa between the levers23, adjacent the ends o the beam 2, so that when the operator isoccupying the seat, either or both of the In operation, both ofthe-levers are moved forwardly, thereby lowering the blade 3 in with theeartlis surface, so that jgrader is moved forward, a certain ortion othe soil will be loosened by the lade'and carried to a given point.

Should a stone or tered adjacent'one end ofthe blade, the lever adjacentthat end of the blade, is moved rearwardly, which will elevate that endof the beam 2, until the blade Sis of sufficient height to pass over theobject, when thelever so opgrasped and operated.l

other object be encounerated is again returned to its forward positionand the blade lowered and, likewise,

'when the vgrader is not in use, but is bei moved from place to lace,both of the levers are .moved rearward v, which will result in elevatingthe blade om engagement with the. earths surface.

When one end of the beam 2 is raised, a twisting mo vement is impartedto the frame 1 so that the adjusting bolt 8 will move to one end of thesocket 6, thereby permitting the. axle 13 to. always rest in itshorizontal position and by constructingthe wheels 14 1n the mannershown, it will be seen that said wheels will readily pass below theframe 1 and ermit the grader to be turned in a very sma space.

'hat I claim is:

1. In a grader of the classdescribed, the combination with a frame; of abeam at one bar carried by said plates, ears on said plates end of saidframe, a'blade atl the lower edge of beframe, having sockets therein, a

lwheels vfor said axle and means bifurcated ends pivotally securedbetween said ears, wheels rotatably said bifurcated ends, said wheelsbeing adapt# mounted between l' ,and spaced from said rack, levershaving ed to engage the earths surface, whereby 460 when the-Ievers are'moved over the rack bars, the beaiffwill be correspondin ly raised orlowered, :a latch on said levers ,'"a operate with said rack bars and.means to support the forward end of the -frame.

2. In a grader of the class described, the

combination with a frame, having a beam at one end thereof and means toraise and lower said beam;` of a head at the opposite end of 4 theframe, said head having sockets therein, a guide bar, arms at the upperand lower ends of said guide bar, a pivot pin carried b 'y the lowerarm, adapted to enter thesocketm the lower end of the head, a boltadjustably se- 7 5 cured to the upper armand adapted to enter the socketat the upper end of the head, said apted to coi socketbein? elongated,an axle on the lower u arm and `be ow the pivot pin, wheels on said l toattach draftanimals to y dlmeansv l n n said bar)1 whereby thegraderwill be propelled and guided.

3. In a grader of the class described, the

combination with a frame; of a beam at one. f

end of said frame, braeingl means between saidlframe and beam, platescarried by said beam, rack bars on ing bifurcated lower ends, wheelsrotatably mounted between said bifurc ated ends, means carried by thelevers adapted to. engage the rack bars and hold the beam -in itsadjusted saidplates, levers-pivotally secured to said rack bars, saidlevers havposition, axhead at' the forward end of said arms at the upperand lower en s of said guide bar, a pivot pin in the low er arm, adapt'-ed to enter one of the sockets inthe head, a

ide bar,

end of the head, said socket being elongated,

an axle carried by the lower arm-supporting ,to attach draft animalstothe guide bar.

. vIn testimony whereof I have signed my ioo name'tothis specificationin the presence of e two subscribing witnesses.
